Game of Thrones is bringing in plenty of new players on for season five.

Fans still mourning the late Prince Oberyn (Pedro Pascal), take comfort: Plenty of his family will be popping up in the new season, and they all seem to love weapons as much as he did.

The HBO show revealed the new castmembers at Comic-Con on Friday, where fans were treated to a sizzle reel teasing the upcoming season, currently in production overseas. (Read our full recap of the panel here.)

Here's a breakdown of the cast:

Alexander Siddig will play Doran Martell, the ruling lord of Dorne and the older brother to Oberyn. He's described as even-tempered, but his subjects are waiting to see if that'll remain true after his brother's brutal death. Siddig is best known for playing Dr. Bashir on Star Trek: Deep Space Nine. (Let geeks rejoice.)

Toby Sebastian will play Trystane Martell, Doran's son and heir to Dorne. He's also one of the reasons Cersei and Jaime's daughter Myrcella was shipped off to Dorne years ago. He is her betrothed.

Speaking of Myrcella …

Nell Tiger Free will play the young Baratheon (or should we say Lannister?), who hasn't been seen onscreen since season two, when she was played by Aimee Richardson. Things aren't exactly going well for Myrcella in Dorne. Thanks to the death of Oberyn, her position is tenuous.

DeObia Oparei is taking on the role of Areo Hotah, a trusted captain in Doran Martell’s palace guard. We hear he's good with a longaxe. Oparei previously appeared as Gunner in Pirates of the Caribbean: On Stranger Tides.

We've also got Enzo Cilenti as Yezzan, who was a wealthy slaver before Daenerys outlawed the trade.

Back in Dorne, Jessica Henwick will play Nymeria (“Nym”) Sand, the second-eldest bastard daughter of the late Oberyn. Her mother was an Eastern noblewoman and raised Nym to be cultured. While Nym's father liked spears, she prefers the whip.

Rosabell Laurenti Sellers will play Tyene Sand, another daughter of Oberyn. Her mother is Ellaria Sand, his paramour whom Oberyn brought to King's Landing in season four. This family all really like weapons … and her favorites are twin daggers.

And in King's Landing, Jonathan Pryce will play the High Sparrow. He's described as devout and pious. He travels to the capital to serve the poor and downtrodden, and quickly amasses a big following. Seems like the type of thing Cersei would not approve of.
